CHD Elektroservis - Stereo Bucket Brigade FX Unit

BBD circuit based analog stereo effect processor with 2 BBD circuits.

Stereo Bucket Brigade FX Unit is designed for Eurorack modular synthesizer systems.

2 genuine analogue BBD circuits (2x1024 stages).
Stereo output (imc. switchable modulation phase).
Internal LFO.
Mixed Output with "Dry/Wet" balance control.
External CV input for Delay length and modulation.
Chorus, Phaser, Flanger, Vibrato, Ensemble effects.
Stainless steel front panel.
Pure analogue circuitry (no DSP technology is used).
Fully hand-made - each module is tested and adjusted individually.

All controls, signal inputs and outputs are located on the front panel. Inputs and outputs use standard mono 3,5 mm (1/8") mini-jack patch connectors:
DELAY block:
MANUAL - manual delay control
EXT-CV - external CV control input

MODULATION block:
+/- - modulation polarity indicator
DEPTH - modulation depth control
EXT-MOD - external modulation control input
0° / 180° - modulation signal phase
INT-MOD - internal LFO speed

AUDIO block:
OVERLOAD - overload indication
GAIN - input gain control
INPUT - audio signal input
FEEDBACK - feedback level
MIX - wet / dry signal ratio
OUTPUT-RIGHT - right audio channel output
OUTPUT-LEFT - left audio channel output

Mechanical dimensions
Module width: 12 HU (60,5 mm)
Module height: 3 U (128,5 mm)
Module site depth: 64 mm (without power supply cable)
Power supply
Supply voltage: +-12 V from the system bus
Current requirement: max +55 mA / +12 V
max -25 mA / -12 V
Inputs / outputs
Inputs: AUDIO-IN -> min +-2,5 VPP for full driving / ZIN = 10 kOhm
EXT-CV -> 0 to +8 V for full driving / ZIN = 10 kOhm
EXT-MOD -> min +-2,5 VPP for full driving / ZIN = 10 kOhm
Outputs: OUTPUT-LEFT -> +-2,5 VPP / ZOUT = 200 Ohm (conforms to standard line level +4 dB)
OUTPUT-RIGHT -> +-2,5 VPP / ZOUT = 200 Ohm (conforms to standard line level +4 dB)
Accessory
Ribbon power supply cable with 10 / 16 pin connectors, length ca 200 mm
